120! Equilateral Triangles and Equidistant Sequences
The above triangle shows the first 171 digits of 120! (factorial). It also shows all the Equilateral Triangles with the numbers 6-6-8 for the vertices of each triangle and all the Equidistant Sequences containing the numbers 6-6-8 that are evenly spaced apart on the same line. Notice that all occurrences of the number 6 in the above triangle are either a part of an Equilateral Triangle or Equidistant Sequence. Select Equidistant Sequences in 10 x 10 square grid.
Let me know if you happen to find other Equilateral Triangles or Equidistant Sequences in the above triangle containing the numbers 6-6-8.
