e and pi together in that rectangle...............and in the columns...vertical lines......there are four of them..........like 4 primes under 100....................who matches...single to double digits....like the critical line.....1/2......one number matches a 2 number......in 67.....the single digit is 7......the double digit is the 6.......the tens digit..........very much 68%......the 1st stand dev from the norm...

67, 71....is also like e.........b/c e starts out....2.71..........and when combined with 89, 97, the other prime pair under 100 to match its single digit to the next prime's double digit......

89, 97
67, 71.........two 71's....a horizontal and a vertical...................at the one in the bottom, right corner.......71 across......a horizontal.....and 71 down.......a vertical..
