I am in the process of putting together a triplet patterned rear wheel myself. I have a 32 hole hub, which I will lace 8 spokes 1x NDS and 16 spokes 3x DS, to a standard 24 holed rim. My NDS, like yours, was not a problem.
But to calculate my DS I had to put my rim and hub measurements into spokecalc, then set it to 48 spoke 5x.
This gave me 275.5, but an addition adjustment (dont know?) gives the correct 273.8
The triplet lacing formula used was originally concieved by a guy called Jeremy from Alchemy Bicycle works. Might be worth sending him an E-mail, their component prices are certainly good (US though).

Most of my knowledge on triplet lacing is stolen from this thread.
