Group theory 10: Burnside's lemma

[@SmallWave80]

Thanks. Many new illustrations and applications. I used to read J. S. Milne's online lecture notes.

18:46 A minor misstep here: 384 should've been multiplied by 1, because the correspondent conjugacy class has only 1 element. :)

Delightful. Hoping it becomes cult viewing. Minor typo at 18:55 - 40320+0+768+24+1528 = 42640 not 42256.

Why is there 768 in the third row though? Shouldn't it be just 384 because this conjugacy class contains only one element?

@@Axi334 yes, this is correct, so that is the error, the result is the right number. He probably knows it by heart or has it on notes on the side.

Great lecture! A small typo in that it should have been D_4 not D_8

[@chaoshengzhe]

both conventions are used by mathematicians. (confusing indeed.)

[@reneglzmtz]

@@chaoshengzhe D_2(4) is also used
