Answer 1

Is it the middle, left or right picture?

Answer 2

Rn*Rm does not seem to be a standard notation. What does it represent in this context?

Answer 3

sounds like some permutation jargon .... but its still unclear what your spose to do with it

Answer 4

"m" looks like a (reflection?), and "n" looks like an identity

but different authors compose their functions in different ways; some read left to right while others read right to left

Answer 5

but since "n" does absolutely nothing that i can tell; its just simplifies to "m" ..... best guess for me then is the middle
