Sep 10, 2012 at 5:56 comment added grp @Igor Rivin: My belief was based on my expertise in the relevant math, but I concede it was just an educated guess (which seems to have been correct, but that's beside the point). More importantly, the mixture of English errors in the question and the "name" of the OP suggest that English fluency (as opposed to English proficiency) may be missing here, hence my Jeopardy joke. Math is universal, yet MO practice leaves little choice but to post questions in English, and I think in cases lacking English fluency one should cut the OP some slack if an expert can surmise the likely intent.
