Properties

Appears in sequences

• Consider the concatenation of n consecutive integers S, S+1, S+2, ..., S+n-1, written in base 2 and then converted to base 10; a(n) gives (in base 10) the first prime reached for any value of S, or -1 if a prime is never reached.at n=6A269710
• Square array A(m,n) = number whose binary expansion is the concatenation of those of { m, m+1, ..., m+n }, with m, n >= 1, read by falling antidiagonals.at n=30A285806
• Prime numbersat n=267763
