Asunto: [mg91093] Find count of binary number pattern within =
concatenated
number

Math folks,

Can someone tell me how to find the count of the occurrences of "1101"
within "11011100101110111100010011010101111001101" generated with the
FromDigits statements below? I will be increasing "n".

n=13

FromDigits[Flatten[IntegerDigits[Range[n],2]]]

11011100101110111100010011010101111001101.

FromDigits[IntegerDigits[n, 2]]

1101

Diana
