Table 2.
Phylogroup set symbol | Feature count |
U = Universal set | 8,390,656 |
V = A ∪ B1 ∪ B2 ∪ D ∪ E ∪ A | 8,224,172 |
V′ | 166,484 |
A | 2,727,759 |
B1 | 2,848,252 |
B2 | 2,691,012 |
D | 2,742,919 |
E | 3,505,791 |
S | 2,153,098 |
The set notation corresponds to the features in each phylogroup. ∪ is the union, and V′ represents the complement of V, i.e., those features not present in V but part of U.
