So...
I don't know if I'm the first saying this but the Super-Tri glyph appears when your checkpoint is in D04 and you die. Don't believe me? Start a new Mombasa Streets game on Easy, run to D04, check to see if the Super-Tri is there (it wont be), get a checkpoint in D04 (don't fight for 2 minutes) and kill yourself (in D04 or not, it doesn't matter). The Super-Tri is now there for your viewing pleasure.
So, what about the Super-Di and the Super-Mono (which I have NEVER seen by myself)? Maybe they appear when you get a checkpoint in a district (DXX) and die in the same district (DXX), or maybe they appear when you get a checkpoint in a district (DXX) and die in another district DYY).
WE should try to find what district DXX and DYY are.
So... any questions? Any ideas?
EDIT:
So.. let's get this going on.
There are 64 possible combinations (checkpoint district - death district):
00 - 00 03 - 00 04 - 00 05 - 00 06 - 00 08 - 00 09 - 00 10-00
00 - 03 03 - 03 04 - 03 05 - 03 06 - 03 08 - 03 09 - 03 10-03
00 - 04 03 - 04 04 - 04 05 - 04 06 - 04 08 - 04 09 - 04 10-04
00 - 05 03 - 05 04 - 05 05 - 05 06 - 05 08 - 05 09 - 05 10-05
00 - 06 03 - 06 04 - 06 05 - 06 06 - 06 08 - 06 09 - 06 10-06
00 - 08 03 - 08 04 - 08 05 - 08 06 - 08 08 - 08 09 - 08 10-08
00 - 09 03 - 09 04 - 09 05 - 09 06 - 09 08 - 09 09 - 09 10-09
00 - 10 03 - 10 04 - 10 05 - 10 06 - 10 08 - 10 09 - 10 10-10
We know that 04 - 04 produces the Super-Tri Glyph, which means we need to test 63 combinations.
It shouldn't be too hard if we divided this by everyone...
Oh: because when testing some combinations you have to travel a lot, you need to fight a bit (hurt a little, BE HURT, etc.) so you don't get a checkpoint.
