I have to wonder whether there's a magma where equation 4 holds while equation 7 (commutativity) doesn't. Off the top of my head, I can't think of one but does that mean there absolutely can't be one, like the depicted graph implies?
- NooneAtAll3 2y agoyou mean the opposite way? article gives proof why 4 implies 7 (thus magma with eq4 always agrees with eq7)
