EXAMPLE

177, 183, 189, 195, 203, 217, 259, 261 are successive odd split numbers. So , so their difference sequence of first differences is 6, 6, 6, 8, 14, 42 and , 2.

NAME

First differences of odd split numbers (A036382).

DATA

12, 2, 4, 26, 4, 6, 2, 10, 4, 2, 12, 24, 4, 2, 6, 2, 2, 2, 8, 4, 2, 4, 10, 2, 6, 6, 6, 8, 14, 42, 2, 4, 2, 6, 2, 4, 6, 2, 4, 4, 2, 2, 2, 2, 2, 4, 6, 4, 2, 4, 2, 2, 10, 2, 4, 6, 6, 6, 8, 4, 2, 4, 4, 14, 4, 10, 14, 8, 30, 48, 2, 2, 2, 6, 2, 4, 2, 2, 2, 2, 4, 2, 4, 2, 2, 2, 4, 2, 4, 2, 6, 2, 4, 2, 2, 2, 4, 2

OFFSET

1,1

COMMENTS

The large local maxima are near powers of 2. Compare the differences of connected numbers (A036379).

Densities of connected (A029827) and split (A036382) numbers seem to behave in opposite way: where connected are dense, split ones are rare and vice versa.

EXAMPLE

177,183,189,195,203,217,259,261 are successive odd split numbers. So their difference sequence is 6,6,6,8,14,42 and 2.
