- diffhist Heawood family 03:43 +49 Kevin Lamoreau talk contribs (polishing my previous edit (including a spelling fix))
- diffhist Heawood family 03:26 +244 Kevin Lamoreau talk contribs (take 2 of the following edit: added note clarifying that there are preservations of knotless or knotted status of either ΔY- or YΔ-transformations, but only one way for either status, with an added point about minor minimality of knotted graphs (which is preserved by the same YΔ-transformations which preserve knotlessness); also got rid of a paragraph break in the syntax that didn't function as one)

- diffhist Heawood family 02:50 +14 Kevin Lamoreau talk contribs (→The \{K_7,K_{3,3,1,1}\}-family: added a qualifier to my statement about certain graphs only generating each other (restricting graphs to being simple (and loopless, although that's unstated as generally assumed) graphs))
- diffhist Heawood family 02:45 0 Kevin Lamoreau talk contribs (→The \{K_7,K_{3,3,1,1}\}-family: reordering of the conjecture regarding the graphs generated by K7 and K3,3,1,1 to be more consistent with the layout under my previous edit)
- diffhist Heawood family 02:43 +381 Kevin Lamoreau talk contribs (→The \{K_7,K_{3,3,1,1}\}-family: added some more examples of broadly similarly constructed families to the larger-defined Heawood family which are the excluded minors for classes of graphs including those based on maximum Colin de Verdière graph invariant)
