/*
 * Lucasian criteria for primality
 *
 * The following table is taken from:
 *
 *	"Lucasian Criteria for the Primality of N=h*2^n-1", by Hans Riesel,
 *	Mathematics of Computation, Vol 23 #108, p 872.
 *
 * The index of the *_val[] arrays correspond to the v(1) values found
 * in the table.  That is, for v(1) == x:
 *
 *	D == d_val[x]
 *	a == a_val[x]
 *	b == b_val[x]
 *	r == r_val[x]		(r == abs(a^2 - b^2*D))
 *
 *
 * Note that when *_val[i] is not a number, the related v(1) value
 * is not found in Table 1.
