The numbers for the explicit representation include the input and the numbers for the implicit representation include the $\mathsf{BWT}$ stored in a wavelet tree. The suffix -c1 means that the bit vectors $B_l$ and $B_r$ of the implicit representation are compressed, and the suffix -c2 means that additionally the (bit vectors in the) wavelet tree are compressed
