A193995 concerns the counting convention used when iterating the sum-of-squares-of-digits map to determine whether an integer is happy. While reviewing the entry, its examples, and the accompanying implementation, I noticed that several closely related ideas were being described in ways that could be read interchangeably: terms in the generated sequence, iterations of the map, and the point at which enough information has been obtained to decide the result.
I traced the implementation and compared the counting convention with the surrounding description and related OEIS material, then submitted a clarification making the stopping and counting convention more explicit. The proposed changes were reviewed and published by OEIS editor Sean A. Irvine on September 6, 2026.
What needed clarification
The issue was not a wrong numerical value, but ambiguity in the terminology used to describe the count. The implementation follows iterations until a previously seen value is reached, while surrounding wording could be read as counting terms of the generated sequence. Those conventions are not identical, so the distinction matters when examples and code are compared.
Published revision
After checking the implementation and related material, I submitted the clarification to OEIS. Sean A. Irvine reviewed the change, and OEIS confirmed on September 6, 2026 that my changes to A193995 had been published.
