For any prime p there are exactly two non-abelian groups of order p³: 1. The Heisenberg group of the field with the p elements, which consists of matrices of the form [1 a c] [0 1 b] [0 0 1] with a, b, c in Fₚ. 2. The semidirect product Z/p
Fix a primitive \(q\)th root of unity \(\xi\) and take \(g\in Sp(2m)\) with eigenvalues \(\xi^{\pm1},\dots,\xi^{\pm m}\), \(1\le m<q/2\). Every character of \(Sp(2m)\) at \(g\) is an algebraic integer of the real cyclotomic field \(\mathbb{

#representationtheory across platforms
every network with a public tag surfaceFollow #representationtheory straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/representationtheory
