(disregard the previous reply if it appears on your end, it has disappeared for me)

The code in my original kumite fork returns true for the test you mention. It must be something to do with the changes made to resolve the repeating names thing.

Regarding turning this into a kata, my thought is that inputs should be guaranteed valid (eg no item in the rules refers to a nonexistent family, no repeating members in the list, no member wants to sit next to themself, etc)

Do you have a link to your updated set of tests? That would be helpful.

Fixed, thank you.

Ah yes I see that now

Are these the same? https://www.codewars.com/kata/5263c6999e0f40dee200059d :/

Haven't done either kata, so I can't say for sure, but raising an issue just in case

"Expected actual value true to approximately equal expected value false (accepted relative error: 1e-9)" as if booleans can not quite be the same as another boolean but still be close enough

Probably not an issue but it's definitely worth mentioning :)
