  • Seventy is the smallest Numberblock to have light red blocks.
  • The main reason why Seventy's red Ten blocks aren't white like Ten is primarily because it needs to fit in with the other 6 tens, which are lighter shades of the rainbow.
  • As of Season 8, 70 is the smallest figured-out Numberblock debuting before all of their divisors have been figured-out.
  • He is the first and only Numberblock so far who has never made non-rectangular arrangements anywhere.
    • However, if the intermediate arrangements seen for one frame during rearrangement doesn't count, then Fifty is the first.
