As time goes on, I grow more disillusioned with quantum field theory.

Out of curiosity, why did you call it "LetL" ?

comment Recognizing special cases of a defined function for permuted arguments
This is better, but the invariance of the function $f$ isn't for permutations of first three arguments $a,b,c$ independent of the second three $x,y,z$. They are tied together. But no problem; your answer and @BobHanlon's answer pointed me in the right direction: I could declare SetAttributes[f1, Orderless] but with the arguments arranged f1[{a_,x_},{b_,y_},{c_,z_}], and make the library of special cases for f1. Then finally, I put f[a_,b_,c_,d_,e_,f_] = f1[{a,x},{b,y},{c,z}]. I tried a few cases and it seems to work. What do you think?

This won't work because $f$ isn't completely orderless among all six variables.

comment Define PolyLog so that positive reals evaluate on upper edge of branch cut
@Öskå These won't do; I need to be able to use this analytically too. See the edit.
