The gathering

The gathering is equal to (grand gorgonghoulgog2 − blasphemorgulus2 + grand gorgonghoulgog + blasphemorgulus)/2.

Unlike almost all other Saibianisms, it is not a perfect power: Its prime factorization starts with 2log10(blasphemorgulus)−1 × 5log10(blasphemorgulus) × …, where due to convergence of final digits, all other prime factors are at least googological close to a blasphemorgulus.
