 May19 answered Logic Puzzle of the age of three sons May18 revised Solving an equation with the same variable twice Removed my unnecessary editor's note. May18 suggested approved edit on Solving an equation with the same variable twice May18 revised Solving an equation with the same variable twice LaTeX formatting. May18 suggested approved edit on Solving an equation with the same variable twice May18 awarded Nice Answer May18 comment How many 10 letter 'words' can be made with no repeated letters and at least 8 consonants? Note to everyone: this is similar to math.stackexchange.com/questions/39428/… , but it's different enough that I think it warrants its own solution. May18 comment Counting number of distinct regions with intersecting circles @soandos: Yes, "exterior" does mean the space occupied by no circles, so your "13" is correct. Also, as the OEIS entry makes no mention of the size of the circles, I think it's any sized circles. May18 comment $n$ by $n$ Primally Magic Squares @Jacob: Nice links! Those are not quite what I'm going for here though; my condition is merely that each column, row, and diagonal needs to be prime in at least one direction, not both as they did. May17 comment calculate location on an isometric world map Actually, u and v are Cartesian values as well. Also, that image seems to be a rotate-then-transform kind of thing, so my formulas may be wrong, although I haven't checked. May17 comment (Non-)Conservative Vector Fields @joriki: Apologies if it seems I have been inattentive or inconsiderate, but I have merely been pondering your reply. :) May17 comment Cube skeleton bindings @Jim Conant: If edges connecting opposite vertices in the octahedron weren't included, then only 4 of my solutions could be found. Also, the dividing-by-the-automorphisms comes from my mathematical idealization of a physical scenario... :P May17 comment Cube skeleton bindings @Jim Conant: By 1-skeleton, you mean an octahedron with opposite vertices also connected, yes? Also, I'm actually more concerned with the number of solutions; enumeration is more easily accomplished with a computer program. May17 comment Cube skeleton bindings @Jim Conant: Extending it to other solids is precisely why I asked for an analytical method... :P To be more accurate, any polyhedron with an even number of faces can be done this way.
