MiracleDinner, this seed 5148563599334434 works in 1.12 and has a complete end portal at coords 450 18 -2260, obviously this is pretty far from spawn but does bypass accessing the nether, unfortunately having this knowledge seemingly invalidates the seed as according to the rules

• You may not use any Minecraft mod or software external to Minecraft that can generate a map of the seed or obtain information about the world in any way other than exploration in the created world (you cannot copy the world and explore it in another save).

I agree that using linear algebra to solve the equations to locate perfect strongholds is not technically using external software other than mental maths, if you would like to share the equations I would love to take a look at them as currently studying maths at uni so this is my jam lol

Why is it that people don't run seeds with complete end portals in set seed glitchless? Also (not a runner with no intent to cheat) isn't the rule to disallow analysing seeds before choosing one pretty unenforceable?
