Desgleichen mit Hinzuziehung von A1, B1: a111 = b101 = c110 = l1, a11 = b01 = c10 = l, a101 = b111 = c1, a01 = b11 = c, a110 = c111 = b1, a10 = c11 = b, b110 = c01 = a, b110 = c101 = a1, d01 = d10 = a l, d101 = d110 = a1 + l1, e01 = f10 = a1 l, e101 = f110 = a + l1, e10 = f01 = a l1, e110 = f101 = a1 + l, g01 = α01 = a1 c1 l1, g101 = α101 = a + c + l, g10 = α10 = a1 b1 l1, g110 = α110 = a + b + l, g11 = α11 = b1 c1 l1, g111 = α111 = b + c + l, β01 = a1 c1 l, β101 = a + c + l1, β10 = a b1 l1, β110 = a1 + b + l, β11 = b1 c l1, β111 = b + c1 + l, γ01 = a c1 l1, γ101 = a1 + c + l, γ10 = a1 b1 l, γ110 = a + b + l1, γ11 = b c1 l1, γ111 = b1 + c + l, δ01 = a c1 l, δ101 = a1 + c + l1, δ10 = a b1 l, δ110 = a1 + b + l1, δ11 = b c l1, δ111 = b1 + c1 + l. Zwischen den vier primitiven Aussagen a, c, b, l selbst besteht übrigens eine Relation, nämlich diese: a1 + c1 + b1 + l1 = i, also auch a b c l = 0 zufolge des Theorems 34+) und 3̅2̅).
