The mnemonic I would use is that the ^ looks like the bottom of an x (for cross product) and the | is an outer key on the keyboard, also indicative of the side of a matrix (which is the result of an outer product). The & for "how much do this AND that have in common" works for me. -- You received this message because you are subscribed to the Google Groups "sympy" group.
