One thing that will probably speed things enormously
is to not grow objects (all.triplets, etc.). Instead create
them to be roughly the right size and do something like

I have a list (length 750), each element containing a vector of unique
strings (unique gene ids), with length up to ~40 (median 15). I want to
compile a matrix of all possible triplets and their frequency within
gene elements. Using combn and a lot of looping, I am accomplishing this
but it is
