$BP$-Adams Novikov Spectral Sequence or Homotopy groups of $S/3$

Question

What is know about the homotopy groups of $S/3$ where $S/3 = \mathrm{hocofib}(S \xrightarrow{\cdot 3} S)$? Otherwise, is there some reference I can consult for the $BP$-ANSS for $S/3$?

Answer 1

For $3$-primary homotopy of $S$ there is early work by

Nakamura, Osamu
Some differentials in the mod 3 Adams spectral sequence.
Bull. Sci. Engrg. Div. Univ. Ryukyus Math. Natur. Sci. No. 19 (1975), 1–25. 

and

Tangora, Martin (4-OX)
Some homotopy groups mod 3. Conference on homotopy theory (Evanston, Ill., 1974), 227–245,
Notas Mat. Simpos., 1, Soc. Mat. Mexicana, México, 1975.

through degree 103, extended to degree 108 by Ravenel in his green book, but beware of some issues in that extended range. There is ongoing work by Eva Belmont on this that uses modern machine computations.

From these 3-local results you can backtrack to extract quite a lot of information on $\pi_*(S/3)$. If you need to go further, maybe try
