Hello, Bonjour, Salut
Hi everybody, thank you for visiting !
There are four fundamental rules for a Wikipedian:
- 1) I am not necessary
- 2) The article is not necessary
- 3) Wikipedia is not necessary
- 4) Keep hydrated !
Oh! I am still a fan of Combinatorial species
BTW, what happened in the book ?
When defining the multi-sort on multi-sets, i.e. disjoint unions instead of unions, it was a huge loss.
PIE was lost, and multi-labelling was lost.
Items like aces of spades, that are both aces and spades, were outed and they missed the party.
