Galois groups of p-class towers of number fields have long been a mystery,
but recent calculations have led to glimpses of a rich theory behind them,
involving Galois actions on trees, families of groups whose derived series
have finite index, families of deficiency zero p-groups approximated by
p-adic analytic groups, and so on.
