Historical Note on Euler Lucky Number
When Charles Babbage built a trial version of his analytical engine, he set it to work calculating a list of values of Euler lucky numbers.
David Brewster reported:
- thirty-two numbers of the same table were calculated in the space of two minutes and thirty seconds; and as these contained eighty-two figures, the engine produced thirty-three figures every minute, or more than one figure in every two seconds. On another occasion it produced forty-four figures per minute. This rate of computation could be maintained for any length of time; and it is probable that few writers are able to copy with equal speed for many hours together.
