5.0 83 0 96 91 35 0 82 8 = Pi{3.14} * phi{1.618} ergo as follows,

25.83 78 74 23 21 17 40 25 67 13 76 28 55 84 = 5.0 83 0 96 91 35 0 82 8^2


25 is the first non-prime{ NP }number that fills a space that would have been a prime number as seen in the follows sequence of the twin primes on the prime number line see as top line in graphics pattern later on this page;


5-7, 11-13, 17-19, 23-25{NP}

0.51 52 86 62 42 0 = 1.618{phi{5}} / 3.14 { Pi }
1.94 16 51 82 54 57 22 = Pi{ 3.14 } / phi{ 3.618}
5.0 83 0 96 91 35 0 82 8 = Pi{3.14} * phi{1.618}
