strandsL(ZZ,List)
strandsL(ZZ,List)  strand span as a subset of [0,n]
Synopsis
Function:
strandsL
Usage:
strandsL(n,D)
Inputs:
n
,
an
integer
, to give the interval [0,n]
D
,
a
list
, a sequence of integers, called a degree sequence
Outputs:
an
integer
, strand span of the subset D of [0,n]
Description
This is one less than the number of strands of D as a subset of [0,n]. Note that some of the strands may be empty.
i1 : n = 5 o1 = 5
i2 : D = {1,2,5} o2 = {1, 2, 5} o2 : List
i3 : strandsL(n,D) o3 = 3
