3^3, which is just cool. (26 was just boring numerically.)
Looking through 777, 27 is also the path between Netzach and Hod (the Hebrew letter Peh, meaning mouth, and the tarot trump The Tower). The colors descending through the scales are scarlet, red, venetian red, and bright red rayed azure or emerald. Associated with Horus, Mentu, Ares, and Mars. The horse, the bear, and the wolf; absinthe and rue; the ruby, or any red stone. The weapon is the sword. Perfumes are pepper, dragon's blood, or any hot pungent odor.
(interesting; that all follows naturally from the path of Peh, but I wasn't sure how it got from 27 to Peh, because it's the 17th letter, and means 70. But if you count the paths after the sephiroth themselves, you add 10 and 17 becomes 27. Spiffy.
The association with 70 is also cool for other reasons which I won't go into here.
But I think it will be a good year. (Note to self to check out the correspondences to 26, see how those match up with this last year.)
Thiiiiiiis.... iiiiiiiis..... myyyyyyy..... birthday song! It isn't very long.
