NAME

Rearrangement of primes such that the absolute value of successive differences is unique. absolute[a(k)-a(k-1)] = absolute[a(m)-a(m-1)] iff k = m. In the process the priority of the smallest eligible prime not included earlier is > the smallest successive difference that has not occurred earlier.

Erroneous version of A084331.

OFFSET

0,1,1

COMMENTS

The sequence of successive difference is 1,2,6,4,10,12,16,18,8,14,22,40,24,28,30,20,36,44,26,32,42,38,60,...

EXAMPLE

After 11 it is 7 as the difference 4 has not occurred earrlier, After 29 it is 13 as the the difference 16 has not occurred earlier.
