 OFFSET 1,1 COMMENTS This is a subsequence of terms in A369274: The smaller of two consecutive terms there. Conjecture: there is no followup sequence with sin(k) < sin(k+1) < ... < sin(k+5), i.e., there are no two consecutive integers in this sequence. It appears that, starting at n=4, a(n) mod 2 has a period of 16 with a periodic part consisting of 8 ones followed by 8 zeros. Similarly, starting at n=4, a(n) mod 4 has a period of 32 with a periodic part consisting of 8 threes followed by 8 zeros followed by 8 ones followed by 8 twos. Tested to 5688 terms. - Gary Detlefs, Jan 20 2024 LINKS Table of n, a(n) for n=1..52. MATHEMATICA Select[Range[0, 2350], Sin[#]
