Not getting cliques for two classifier which are not significantly different

[BINAYKUMAR943]

Below is the result when I am trying to compare four different classifiers.

['CoEye' 'TSF' 'cBOSS' 'Mr-SEQL']
CoEye 5.0
Mr-SEQL 61.0
TSF 8.0
cBOSS 10.0
dtype: float64
CoEye 3.279570
TSF 2.559140
cBOSS 2.537634
Mr-SEQL 1.623656
dtype: float64
('CoEye', 'Mr-SEQL', 1.6071230220582003e-11, True)
('Mr-SEQL', 'TSF', 1.5905280411437273e-07, True)
('Mr-SEQL', 'cBOSS', 1.3264426790567074e-06, True)
('CoEye', 'TSF', 1.6515911035945563e-05, True)
('CoEye', 'cBOSS', 4.231130849948383e-05, True)
('TSF', 'cBOSS', 0.4035623277672452, False)
Index(['CoEye', 'TSF', 'cBOSS', 'Mr-SEQL'], dtype='object')
[1, 2]

From the above result, it is clear that classifiers TSF and cBOSS are not significantly different. But I am not getting any clique for them in the CD.
Below is the CD diagram obtained.

I am not quite sure, but can you try adding more classifiers since 4 is not enough maybe ?
Since the test is also based on friedmann

Due to the assumption that the test statistic has a chi squared distribution, the p-value is only reliable for n > 10 and more than 6 repeated measurements.
