Stats question - Tukey homogeneous subsets

Q

I ran an ANOVA with Tukey post test and would now like to know for my graphic the homogeneous subsets. I found already out that running the test with SPSS there is an automatic outset of the homogeneous subsets.

But is there as well a way to determine them with certainty manually as I dont have access to SPSS and my statistic program seems to not be able to give me these subsets?
