Am I missing something here?

1000000145 = 5 * 59 * 911 * 61^2

That looks very unsquare-free to me. Why is it that all of the solutions seem to have it included in the list of square-free numbers? The racket solution has unit tests to labour the point that this is wrong. --Tim-brown (talk) 18:46, 6 January 2019 (UTC)

- Hi Tim,

- The number to be tested is one
**trillion** one hundred forty five i.e. 1,000,000,000,145. Your number is one **billion** one hundred forty five i.e. 1,000,000,145.--PureFox (talk) 20:30, 6 January 2019 (UTC)

- Thanks purefox. However, I cut and pasted this number from other implemtations' output. I'll fix my 1e9 -> 1e12... But I think others will need to check their respective values of a trillion. --Tim-brown (talk) 22:24, 6 January 2019 (UTC)
