    Is there a number 21 in Pi?

    Answer

    In Pi, 21 first appears at position
    93

    115 times in the first 10,000 digits

    Searched in the first 10,000 digits after the decimal point, position 1 = the 1 in 3.14…, overlaps counted. If the digits were independent and equally likely, a 2-digit block would be expected about 100 times there.

    Positions 91–100

    ↑ 93

    Also at positions 102, 173, 280, 380, 423, 524, 546, 565, 650, 711 and 104 more.
