This sequence, of length 1112 (close to the current record) may be of interest because it was derived differently from the 1124 sequences, by a depth-first search starting with a sequence of length 974 satisfying 1=-2=-5 and 11=-13 exactly:

As expected the subsequence structure is very similar to that for the 974 sequence

617: 1 4 10 13 16 19 22 25 27 31 34 40 42 46 52 55 58 64 76 82 85

3478: 2 5 8 11 17 20 21 23 26 29 32 38 41 44 50 54 59 62 65 68 80 83


809: 18 37 45 72 79

3286; 9 36 74


873: 7 28 49 70

3222: 14 35 47 56 77


1458: 3 12 30 39 48 57 66 75

2637: 6 15 24 33 43 51 60 63 69 78


242: 67 845: 73 1266: 53 1430: 84 1833: 61 3314: 71 3506: 81

This reflects the beginning of the subsequences. There are some emerging methods for analysing over the whole length which may give insight into the way in which patterns break up.
