Different displays of a long low-discrepancy sequence

It would be good to have some long sequences with low discrepancy displayed nicely here (or on subsidiary pages) in tabular form, together with discussions about the structures that can be found in these sequences. For now, here is the current record not displayed in a particularly helpful way. It is a sequence of discrepancy 2 and length 1124.

The raw sequence

+ - + + - - - - + + - + + + - - + - + + - - - + - + + - + - - + + - + - - + - - + + - + + - - - + + + - - + - + - - + + + + - - + - - + + - - + + + - - + + - + - - + - - + + - + - - + - + + + - - + - + - - + + - - - + + - + + + - - - + - - + - + + + + - - - - + + - + + + - - + - - + - - + - + - + + - + + + - - - - + + + + - - - + + - + - - + - + + - - + - + + - + - + - + + - - - + + - + + - - + - - + - - + + + + - + - - + - - + + - - + - + + - - - + - + + - + + + - - + + - - + - - + - + + - - + - + + - + + - - + - - + - + + - - + + - + - + - - + - + + + - - + - + + - - - - + + - - + - + + - + + - - + - + + - - + + - + - - + - + - - + + - - + - + + + - + - - + - + - - + + + + - - - + + - + - - + - + + - - + - + + - + + - - + - - + - + + - - + + - - - + + - - + - + + - + + - - + - - + + + + - - - - + + - + + - + + - - + - - + + - - - + + - + + - - + - + + - + - - - + - + + - + + - - + - - + - + + - - + + - + + + - - - + - + + - + + - - + - - - + + + - - + - + - - + + + - + - + + - + - - - + + - + - + + - - + - - + - + + - - + - + - + + - + - + - - + - + + - - + - - + - + + + - - - + + - + + + - + - - + - + + - - + - + + - + - - - + - + + - + + - - + - - - + + + - - + - + + - - + + - + - + + - + - - - + - - + - + + - - + - + + - + + - - + - + + - + + - - + - - + - + + - - + - - + - + + - + - - + + - + + - - + - - + - + + - - + - + + - + + - - + - + + - - + + - + - - + - + + - - + - - + - + + - - + - + + - + + - + + - - + - + + - - + - - + - + + - - + - + - - + + + - + - - + - + + - - + - + - - + + + - - - + + - + + - - + + - + - + + - - + - - + - - + - + + - + - - + + + - + - - + - + + - - + - + - - + + - - + - + + - + + - - + + - + - - + - - + - + + - + + - - + - + + - + + - - + - - + + + - - - + - - + - + + - - + + + + - + - - + + - - + - + + - - + - - + - + + - - + - + + - + + - - + - - + - + + - - - + + - - + + - - + - + + - + + - - + - - + - + + + - + - - + - + + - - + - + + - + - + - - + - + - + + - - + - + - - + + + - + - - - + + + - - + - - + - + + - - + + + + - + - - - + - + + - + + - - + - - + + + - - - + - - + - + + + - + - + + - + - - - + - - + + + + - - + - + + - - + - + + - + - - + - + + - - - + - - + + - + - + + - + - - - + - + + + + - + - - - - + - + + - + + - - + + - + + - + - - + - + + - + - -

Multiplicativity properties of the 1124 sequence

The 1124 sequence is not weakly multiplicative, but it does appear to be close to a weakly multiplicative sequence. That is, if you are prepared to disregard a few "errors", then the number of distinct HAP-subsequences is 6. One can use this information to identify a quasi-multiplicative sequence that is in some sense close to the 1124 sequence. Some details can be found in the sequences of comments that begin here and here.
