The natural log of e, and fourth power of the imaginary unit i is, for 10 points, what number which is the multiplicative identity, and the only positive integer that is neither prime nor composite?
For a real projective plane or a tetra-hemi-hexahedron, a characteristic symbolized chi is equal to this. The Riemann zeta function evaluated at this argument is identical to the harmonic series. Fermat's Little Theorem states that for a prime number p and any integer a, a to the p minus one is congruent to it mod p, and every square of an odd number, taken modulo 8, is [*] congruent to this number.
