うちの嫁さんは青木悠さんが高校生のときに教えたことがあるという。たまたま聴講生として大学の授業に出ていたら、むこうから「若島先生」と声をかけられたとか。「元気で優秀な子」だったと言ってました。

search prompt: centralizer of an element of a symmetric group
snippet of response:
Example: g = (1,2)(3,4,5) in S_5
* Cycle Type: 2^1 3^1 (one 2-cycle, one 3-cycle)
* Z Factors: Z_1 (for the single 2-cycle) x Z_1 (for the single 3-cycle)
* S factors: S_1 (for the single 2-cycle) x S_1 (for the single 3-cycle)
* Result: C_{S_5}(g)\equiv Z_1 x Z_1 x S_1 x S_1 = {e}, the trivial group (only the identity) because there are no cycles to permute or power.
Example: g = (1,2)(3,4) in S_4
* Cycle Type: 2^2 (two 2-cycles)
* Z Factors: Z_2 (for the two 2-cycle, think powers of (1,2) and (3,4)
* S factors: S_2 (permuting the two 2-cycles, e.g., swapping (1,2) and (3,4))
* Result: C_{S_4}(g)\equiv Z_2 x S_2 (order 2x2=4), which includes e,(1,2),(3,4),(1,2)(3,4) and elements like (1,3)(2,4)
What I've learned from AI is that if you are going to be wrong, do so with an authoritative tone.

Koppa (letter) - Wikipedia
There once was a Greek letter called Koppa: Ϙ. Greeks gave it up as it was redundant with Kappa: K.
Ϙ was saved by the Etruscans, who *really* needed 3 letters for their variations on "K". Then it became Q in the Latin alphabet, and also a delicious pork salumi.
