Absolute values of determinants taken on corresponding pairs of digits of pi and e. Let p(n) denote the nth digit of pi, and let e(n) denote the nth digit of e. Then define a(n) = abs(p(n)*e(n+1) - p(n+1)*e(n)).

	EXAMPLE	`For n = 1, a(1) = abs(37 - 12) = 19 (i.e., the determinant taken on the first pair of digits of pi and e). For n = 2, a(2) = abs(11 - 74) = 27. For n = 3, a(3) = abs(48 - 11) = 31.`
