- diffhist Cross-polytope 20:55 +4 Tamfang talk contribs (→n dimensions: two unrelated uses of 'k' in this row)
- diffhist Group (mathematics) 18:10 −233 Stepwise Continuous Dysfunction talk contribs (trim details that are overkill at this point and just make the introduction harder to read)
- diffhist Group (mathematics) 18:05 −7 Esevoke talk contribs
- diffhist Group (mathematics) 17:59 −9 Esevoke talk contribs (no need for this)

- diffhist Group (mathematics) 17:41 −63 Esevoke talk contribs (per Talk:Group (mathematics))
- diffhist Group (mathematics) 16:15 −60 Stepwise Continuous Dysfunction talk contribs (the opening line had one too many parentheticals, and "closure" is the most unfamiliar and perhaps least necessary of the terms to introduce at this stage)
- diffhist Group (mathematics) 11:21 +87 Esevoke talk contribs (→Further reading: Groups are extremely important in physics, yet this article doesn't tell this fact.)
- diffhist Group (mathematics) 11:17 +39 Esevoke talk contribs (we have an article about this book; also, we should mention quantum mechanics in the article)
- diffhist Group (mathematics) 11:08 +6 Esevoke talk contribs
- diffhist Group (mathematics) 11:07 +86 Esevoke talk contribs (I think this makes it so that even a third grader could get an idea.)
- diffhist Group (mathematics) 11:00 +9 Esevoke talk contribs (saying just "set with an operation" seems weird (with in the sense that they are together?-they laymen will think))
- diffhist Group (mathematics) 10:58 +37 Esevoke talk contribs (they know what a set is, but operation needs a few examples so they don't need to click in the link; these two are very familiar to the laymen)
- diffhist Group (mathematics) 10:10 +286 Esevoke talk contribs (→Further reading: very accessible geometric introduction from a master)
- diffhist Group (mathematics) 10:00 +30 Esevoke talk contribs

- diffhist Group (mathematics) 07:44 +431 Esevoke talk contribs (WP:BEBOLD (I'm trying to clarify the first paragraph with a straightforward example), following I. Gelfand's principle in action: quickly seek the simplest examples revealing the importance and giving more understanding of the concept with "concrete" cases! (feel free to revert me)) Tag: Reverted
- diffhist Group (mathematics) 07:16 +4 Esevoke talk contribs (→First example: the integers)
- diffhist Cross-polytope 02:05 −2,712 Jacobolus talk contribs (trim table past the 6-dimensional case; the entries in this table can be trivially computed from the provided formula, and each additional example has steeply diminishing returns. we don't need it to be wider than a common window width and every extra row makes the article less legible)
- diffhist Cross-polytope 02:02 +117 Jacobolus talk contribs (put low-dimensional examples into a consolidated section)
- diffhist Matrix (mathematics) 02:00 +6 David Eppstein talk contribs (→Computational aspects: change up verb to avoid singular-is-plural)
- diffhist Group (mathematics) 00:24 +27 Esevoke talk contribs (→See also: not mentioned in the article nor in the page List of group theory topics at the "See also" section)

- diffhist Euclidean space 22:12 −112 Gramix13 talk contribs (→Other geometric spaces: Removed split discussion tag.)
- diffhist Group (mathematics) 21:05 +151 JayBeeEll talk contribs (over the last few months the first sentence has slowly gotton terser, and as a result less gentle. Restoring a version from January (minus an unnecessary aside) that uses more words but perhaps has slightly lower expectation of reader familiarity with the concept)
- diffhist Matrix (mathematics) 07:07 +90 David Eppstein talk contribs (→Eigenvalues and eigenvectors: source real matrices w/complex eigenvalues)
- diffhist Group (mathematics) 02:09 +13 David Eppstein talk contribs (Undid revision 1294658633 by 62.3.121.230 (talk) it's a matter of convention but by convention the set comes first) Tag: Undo
- diffhist Group (mathematics) 01:58 −13 62.3.121.230 talk (replaced ordered pair with pair. A group is not an ordered pair of a set and an operation - which would come first, the set or the operation?) Tag: Reverted

- diffhist Matrix (mathematics) 07:19 +349 David Eppstein talk contribs (source vector-matrix-vector product in game theory)
- diffhist Matrix (mathematics) 04:44 +187 David Eppstein talk contribs (→Applications: outcome = vector-matrix-vector product)
- diffhist Matrix (mathematics) 01:50 +196 David Eppstein talk contribs (→Applications: it is false that game-theoretic payoff matrices "merely take advantage of the compact representation of a set of numbers in a matrix": they are used as matrices, in matrix-vector products. Move that example to later and connect it to linear programming (still needs an appropriate source))
