Line 64:
:Maybe because you have or are considering a solution in other bases, this is driving your request? I am questioning it as I would like to understand if I have dumbed the task down too much and truly missed a salient point or if not mentioning the base was enough and maybe more clear for the purposes of the task (not involving bases other than ten). I wish others would add their opinions too :-)<br>--[[User:Paddy3118|Paddy3118]] 06:54, 13 September 2012 (UTC)
:Paddy, be careful what you wish for. The largest truncatable prime in a given base can be estimated by probabalistic methods from the Zeta Function. Computing the largest truncatable prime in several bases and comparing them with the estimated values can be used to gain insight into the Zeta Function and maybe the Reimann Hypothosis.--[[User:Nigel Galloway|Nigel Galloway]] 12:01, 14 September 2012 (UTC)
:While claryfing this task you may wish to be clear if you consider 1 to be a prime number, you should not. From which it follows that 13 is a left reducable prime, but not a right reducable prime.--[[User:Nigel Galloway|Nigel Galloway]] 12:10, 14 September 2012 (UTC)
