Line 8: : (In response to [[User:Nigel Galloway\|Nigel Galloway]]) "...1 is not Magic because 1 divides 1." Perhaps not, but ''effectively'' they may be thought of as being that, because they are magic whether you treat them as being evenly divisible by one or just summarily declare them to be magic. Saying they are magic because "the first n digits are evenly divisible by n" is more defensible than "because I said so" in my opinion. --[[User:Thundergnat\|Thundergnat]] ([[User talk:Thundergnat\|talk]]) 16:26, 10 February 2023 (UTC) :: (In response to [[User:Rdm\|Rdm]]) "If n=1, all positive integers would be magic numbers" False. If n = 1 then all '''single digit''' positive integers would be magic. And they are. "if n=2, half of all positive integers would be magic numbers" False again. If n=2, half of all '''two digit''' positive integers would be magic numbers. And they are. "it's clear that the current task description does not match the referenced OEIS:144688 sequence." In what way? They both contain the same number of values, in fact, consist of the exact same values. In what way do they differ? --[[User:Thundergnat\|Thundergnat]] ([[User talk:Thundergnat\|talk]]) 16:26, 10 February 2023 (UTC) ::: Ok, I missed a clause there. Thanks. --[[User:Rdm\|Rdm]] ([[User talk:Rdm\|talk]]) 18:44, 16 February 2023 (UTC) ::: The OEIS page definition seems to me to be equivalent to the definition on the task page. The OIES page makes explicit that the number with the final digit removed must also be magic (requiring special treatment of the single digit numbers), but that is implicit in the task definition. Explicitly stating the final digit removal must result in a Magic Number is possibly a hint of a way to how to solve the task. --[[User:Tigerofdarkness\|Tigerofdarkness]] ([[User talk:Tigerofdarkness\|talk]]) 20:56, 10 February 2023 (UTC)
