The primorial, denoted p_n#, is a function that multiplies together the first n prime numbers, playing the same role among primes that the factorial plays among all positive integers. For example, the primorial of the first five primes is p_5#, equal to 2 times 3 times 5 times 7 times 11, which equals 2310, and the sequence of primorials begins 1, 2, 6, 30, 210, 2310 and continues to grow rapidly. The term was coined by Harvey Dubner as a deliberate echo of factorial, since primorial relates to primes the way factorial relates to factors.

Is Kind Of Object
Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
