Hi Dan,
<nitpicking>
Therefore,
2×2×2: 26 (power 0.807666)
2×3×3: 21 (power 0.842808)
2×2×4: 14 (power 0.842482)
<nitpicking>
I would not use bear for sample size estimation of replicate designs. Like in FARTSSIE the 2×2×2 sample size n is estimated and the partial replicate’s calculated as ¾n or the full replicate’s as ½n – which is only approximately correct.
In the partial replicate you need a multiple of three subjects ≠ 20. 
Therefore,
2×2×2: 26 (power 0.807666)
2×3×3: 21 (power 0.842808)
2×2×4: 14 (power 0.842482)
