Isomer numbering[edit]
I could not find a complete explicit list of the isomers. By my count there are 14 isomers
- 123 124 125 126 127 128
- 135 136 137 138
- 145 146
- 235 236
but each has 4 possible numberings and I could not figure out the standard ones. (In at least one case I have two refs with different numberings for the same isomer). Help, please, ... All the best, --Jorge Stolfi (talk) 07:41, 22 January 2010 (UTC)
- I have fixed the list in the article but there is a discrepancy with the CRC dictionary. It lists 145 and 148 (which to me look like the same), with different codes, and omits 236. Confused... --Jorge Stolfi (talk) 07:24, 30 January 2010 (UTC)
