| Nov 25, 2012 at 1:12 | comment | added | Geoff Robinson | @Jim: Yes, I have always preferred "solvable" myself, partly a rebellious reaction of a postgraduate student against the Oxford tendency to use "soluble"- though Burnside and P. Hall also used "soluble" and they were in Cambridge long ago. I remember once David Sibley gave some lectures in Oxford about the Character Theory of the Odd Order Paper, which he started with " A finite group is soluble if and only if it can be dissolved in water"! I envy the ability to multitask, and I note your (correct) comment about THE Borel subgroup. | |
