The arithmetic
The range for puzzle #132 contains 2.72 × 1039 private keys. A modern eight-core laptop running this solver checks on the order of four million keys per second, so an exhaustive sweep would take about 2..1 × 1021 years. Searching randomly instead of in order does not change that expectation — it only changes which unlucky order you fail in.
