In the class of planar autonomous quadratic polynomial differential sys- tems we provide 6 different phase portraits having exactly 3 limit cycles surrounding a focus, 5 of them have a unique focus. We also provide 2 different phase portraits hav- ing exactly 3 limit cycles surrounding one focus and 1 limit cycle surrounding another focus. The existence of the exact given number of limit cycles is proved using the Du- lac function. All limit cycles of the given systems can be detected through numerical methods; i.e. the limit cycles have “a normal size” using Perko’s terminology.
