334280 should be replacing 1000336 in the list of terminated sequences
334280 i:5156 = 601 Prime, all is done in the database.

Sorry for taking so long to respond. I have made the suggested change. If you find any others let me know.
If there are any sequences that were once merges but now terminate I suppose we could consider changing them. I am not sure what to mark a sequence if it merges with a lower sequence which then reaches a higher point before terminating.

OK.

these ones could be changed:

1011520 i: 1 = 474750 i: 7; 474750 ends i: 2724 = 43.

311202 ends i: 2729 = 43; 218966 is on downdriver run and is not a starting sequence.

373152 ends i: 4045 = 601 (merge with 6160)

894312 ends i: 6123 = 601 (merge with 6160)

453404 ends i: 3988 = 59 (merge with 334440)

493410 ends i: 4141 = 109 (merge with 228522)

920478 ends i: 5987 = 7 (merge with 163716)

The way I had been marking terminations that were merges with a terminated sequence was as a merge with the terminated sequence. After Wolfgang started updating his site again, I asked him which he prefers and he marks those sequence just as straight terminations, so that's how I started marking them.

I called out the couple that merged with 6160 because Wolfgang calls that sequence out as a pretty famous one and I thought that another sequence that merged with one that terminated so many other linked sequences was noteworthy:

^* I wonder what the top ten for "terminated sequences that other sequences merge into" looks like.....

I will hopefully get to these this weekend. Did you check whether the max hight on any of them increased?

Sorry I have not checked the maximum height in the DB.

101844:i2541 = 638288:i10, so 638288 can be marked as "merge".
