Comments

Values above 600000 (i.e. for n >= 11) were computed by David J. Seal (personal communication) and have not yet (April 2003) been independently confirmed.

Another term added from computations beyond 4100000, up to 22000000 (September 2014). Like those between 600000 and 4100000 reported by Christopher E. Thompson, these have not yet been independently confirmed. Computations done by David J. Seal, Sep 12 2014
