According to [https://www.numbersaplenty.com/set/untouchable_number/ one of the OEIS links] there are 150,232 untouchable numbers up to 1e6 so it looks like the REXX result (150,233) is off by one here.
:::<small>I've corrected the REXX output, the incorrect count was computed with an overreach of '''18''', not '''20'''. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 21:28, 11 February 2021 (UTC)</small>
By running the Go program with a limit of 1e6 and a sieve factor of 20 (up from 14 for 1e5), I was in fact able to verify the figure of 150,232. Factors of 18 and 19 both gave 150,233 so there must be an 'awkward' number within this range which takes some eliminating. --[[User:PureFox|PureFox]] ([[User talk:PureFox|talk]]) 09:36, 11 February 2021 (UTC)
