| Weight class, k ≤ L | 47,450 · 47.45 % |
| Ties, k = L | 0 |
| On the level line L = 1 | 7,192 |
| Forced level, l ≤ d² | 1,067 |
| Range of a(n) | 173 … 71,446,387 |
| Range of the jump d | 98 … 6,664 |

61 different gaps occur, from 98 to 6,664; the level share is 52.55 %; 1.1 % of terms are forced level (l <= d^2); there are no ties.
The decomposition
Every term of a strictly increasing sequence is written a(n) = k(n)·L(n) + d(n): the jump d = a(n+1) − a(n), the weight k the least divisor of a − d greater than d, the level L = (a − d)/k. A term decomposes when a > 2d; it is in the level class when k > L and in the weight class when k ≤ L. See decompwlj.com and arXiv:0711.0865, or how it works, with worked examples and a live one.
