I was able to sort my products in expressions like

aS⁺bc + bS⁺cS^- + cb + others etc

by first setting up a commutation algebra for quantumops S⁺ and  S^-  .  Then when I expanded my expression to get results like above it separates out the operators without using SortProducts

abcS⁺ + bcS⁺S^- + cb + others etc

This is what I wanted. 

 After that, however, I could not get SortProducts to rearrange to coefficients, like abc changes to bac  

But getting there.  Thanks Edgardo!

Hi guys

Thanks for answers and I think they would work, but I found a simple work around since I know the max power, n, of each equation, so just

expand(%);

subs(nx^2 = 1, %);
subs(nx^3 = nx, %);
subs(nx^4 = 1, %);
subs(nx^5 = nx, %);

collect(%, x)

etc

not very elegant, but works
