Well, another obvious extension would be to prolong the vertical line, since it's already ordered by rows (two of them). Or, indeed, you could make an array out of them, making a super-glyph (kind of like a block matrix). Four blocks of four digits would get you to 10^4^4 = 10^16 so 100,00,00,00,00,00,00,00 (or 10000,0000,0000,0000, or 10,000,000,000,000,000 depending on your grouping), which is 10 Quadrillions in short- scale. Obviously grouping digits by blocks of 2 or 4 makes mor sense, since that's a row or a glyph. Interesting discussion though, which is probably the goal here, rather than a good or bad reply: it allows you to see how the candidate thinks or approaches a problem.
