| 8 | ** -- G modified to have y&~z instead of y&z **
|
---|
| 9 | ** -- FF, GG, HH modified to add in last register done **
|

| 10 | ** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
|
---|
| 11 | ** -- distinct additive constant for each step **
|
---|
| 12 | ** -- round 4 added, working mod 7 **
