Sorry, had a transcription error in my last email.
All sets of unit fractions adding to unity given were correct
except the simplest sets for cases n=2, 3:
> {2,3,4,6}
> {5,8,9,10,15,18,20,24}
which of course should have been:
{2,3,6}
{4,5,8,9,10,15,18,20,24}
This correction makes the sequences mentioned begin:
Initial least terms:
{1,2,5,7,17,29,...}
Number of terms:
{1,3,9,24,73,182,...}
Sum of terms:
{1,11,113,835,7524,48639,...}
Also, I wonder if this observation continues to hold for all cases:
> Assuming that the sets of unit fractions that sum to n are
> accumulative, so that the (n+1)-th set contains the n-th set,
> then we can separate these into subsets of unit fractions that sum
> to unity.
