I found several non-beneficial deletions including two using multi-coloring and a couple of ERs. but a xy-wing<19> and a x-wing <4> was all that was required to solve it.

I get no bonus points for 2x ERs w/transport. Sad How about some help Danny.

Always glad to help. Remember, I said finding ... not using.

Code:
 after basics there are these two eliminations -- neither of which is necessary
 each ER w/transport is distinct ... but exist concurrently
