→Number of untouchable numbers up to 1 million
Line 35:
:: Without something reliable to check against, I think that 1 million is probably as far as we can practically go. We could, of course, incrementally increase the sieve factor for higher limits until we ''appear'' to get a stable count but, judging by what it said in the Julia entry, there may still be the possibility of some outlier spoiling the party! --[[User:PureFox|PureFox]] ([[User talk:PureFox|talk]]) 14:23, 11 February 2021 (UTC)
Sorry! Both the REXX and Go entries report 150,2'''5'''2 not 150,2'''3'''2 untouchable numbers <1e6 (ouch!). --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 14:45, 13 February 2021 (UTC)
