the following message is from Dan Hoey: From: Dan Hoey <Hoey at AIC.NRL.Navy.Mil> Neil Sloane mentions that I calculated the probability a[n] of two elements generating S_n. Please note that a[2]=3/4. I accidentally reported this as 1/2 and it's become prevalent. Is a[2] the only one not divisible by 1/n! ? Dan Hoey at AIC.NRL.Navy.Mil MIME-Version: 1.0
