Thanks for the offer.  There are two things I want verified.  First,
is it true that:
      u(1000)=12336
      u(1091)=13533
      u(1210)=14894
      u(1730)=21870
      u(1748)=22151
      u(1947)=24851
      u(1999)=25511 ?
This is with zero-based indexing (u(0)=1, u(1)=2, u(2)=3, ...), so
maybe you need to add 1 to the indices.

Second, letting f(n) = (u(n)/21.6) - floor(u(n)/21.6, for what n in
1000...1999  is  .5 <= f(n) < .55?

Thanks.
