Historical Note on Euler Lucky Number
When built a trial version of his analytical engine, he set it to work calculating a list of values of Euler lucky numbers.

reported:
 *  numbers of the same table were calculated in the space of ; and as these contained figures, the engine produced thirty-three figures every minute, or more than one figure in every two seconds. On another occasion it produced  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.
