Map Quadrant System -- Numbers vs. Letters

Instead of A and B and C and D for the quadrant labels, it can use the
numbers 1 and 2 and 3 and 4. So, for example, the sequence ACDABBCDA
can be written as the number 134122341. See how the number stands for
the letter for each. That way it can still be a number and it is less
digits than the composite of primes version that needs factoring.
1 = A = upper left quadrant.
2 = B = upper right quadrant.
3 = C = lower left quadrant.
4 = D = lower right quadrant.
