(2) Is it not true that in a strict monoidal category if $X\xrightarrow{f}Y\xrightarrow{g}Z$ then $f\square g= g\circ f$? (3) Is the pentagon axiom automatically satisfied in a strict monoidal category? Many thanks for your patience and pointers. [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
