4296 equal divisions of the octave (abbreviated 4296edo or 4296ed2), also called 4296-tone equal temperament (4296tet) or 4296 equal temperament (4296et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 4296 equal parts of about 0.279 ¢ each. Each step represents a frequency ratio of 21/4296, or the 4296th root of 2.
4296edo is an extraordinarily strong 5-limit system, tempering out raider, [71 -99 37⟩, pirate, [-90 -15 49⟩ and the Kirnberger's atom, [161 -84 -12⟩. Not until 73709 do we reach a division with a lower 5-limit relative error, and not until 6796263 do we find a lower logflat badness. It is uniquely consistent through the 9-odd-limit, and in the 7-limit, it tempers out the landscape comma, 250047/250000, and so supports septimal atomic, the 612 & 1848 temperament.
4296 = 12 × 358, and is potentially of use as a device for constructing 5-limit 12-note circulating temperaments, and which means that one cent is exactly 3.58 steps of 4296edo. From that point of view, one might note that 81/80 is 77 steps, 531441/524288, the Pythagorean comma, 84 steps, and 32805/32768, the schisma, 7 steps, making it exactly 1/12 of a Pythagorean comma and 1/11 of a syntonic comma, useful approximations when dealing with this problem. Senior, [-17 62 -35⟩, fortune, [-107 47 14⟩ and the monzisma, [54 -37 2⟩, are all one step of 4296et.
