COMMENT
|
a(n) is A145572(n) (a decimal number with digits only from {0,1}) read as base 2 number converted back into decimal notation.
The sequence of digit lengths is [1,1,2,8,37,217,1518,...]
|
|
FORMULA
|
a(n)=A145572(n) interpreted as number in binary notation, then converted to decimal notation.
|
|
EXAMPLE
|
a(3)=49, because A145572(3)=110001, and the binary number 110001 translates to 2^5+2^4+2^0=32+16+1 = 49.
