Hello Zain,
simple IOS-like ACLs can be converted to EXOS using E2X (
https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-convert-EOS-configurations-to-EXOS-...). More complex IOS ACLs can be converted to EXOS using IOStoEXOSACL (
https://github.com/extremenetworks/ExtremeScripting/blob/master/EXOS/Perl/IOStoEXOSACL).
I used E2X to convert your ACL to the following policy file:
# acl_10.pol
entry 10 {
  if {
    source-address 172.16.66.246/255.255.255.255;
  } then {
    permit;
  }
}
entry 20 {
  if {
    source-address 172.16.66.241/255.255.255.255;
  } then {
    permit;
  }
}
entry 30 {
  if {
    source-address 172.16.72.110/255.255.255.255;
  } then {
    permit;
  }
}
entry 40 {
  if {
    source-address 172.16.72.84/255.255.255.255;
  } then {
    permit;
  }
}
entry 50 {
  if {
    source-address 172.168.202.100/255.255.255.255;
  } then {
    permit;
  }
}
entry 60 {
  if {
    source-address 172.16.72.17/255.255.255.255;
  } then {
    permit;
  }
}
# next entry added to match EOS ACL implicit deny
entry 70 {
  if {
    source-address 0.0.0.0/0;
  } then {
    deny;
  }
}
Best regards,
Erik
